The novel compounds having the above formula(I) according to the present invention have a very strong herbicidal activity and a good selectivity for a useful vegetation.

The compounds of the present invention can be prepared by reactions as described in herein below.

The compounds of general formula(I) can be obtained by hydrolyzing the compounds of following formula(II) with alkali under water, organic solvent or the mixture solution thereof. ##STR15##

In the above reaction scheme of Method 1, Ac is acetyl group, but it may be a protecting group easily dissolved by acid, alkali or others. In order to hydrolyze the above Ac group, alkali base such as NaOH, KOH, LiOH, Na₂ CO₃, K₂ CO₃, etc., preferably LiOH, may be used.

The above reaction of Method I is carried out under water or organic solvent, and also a mixture of water with unreacting solvent such as methanol, ethanol, acetone or THF etc., or solvent alone.

The hydrolysis in the reaction occurs at the temperatures of 0°˜80° C. and the reaction time of 1˜24 hours, and then the obtained product may be easily separated by acidifying with HCl water solution.

As an other process, after acidifying, the obtained product is extracted with methylene chloride, ethyl acetate, etc. then concentrated/crystalized to obtain the final product. If necessary, a pure product can be obtained by purification to column chromatograph.

The compounds of the above formula(I) according to the present invention can be prepared by reacting the compounds having the following formula(II) with alkali at the temperature of 25°˜40° C. (Method 2) ##STR16##

The reaction of process Method 2 may be preferably carried out under alkali such as NaOH etc. of a small quantity. The product may be separated as the same with the above Method I.

The above reaction may be carried out in solvent such as dioxane, aceonitrile, THF, acetone, MC, toluene or butanone, and then the solvent can be used with small amount of strong base such as Dabco(1,4-diazabicyclo[2.2.2]octane), DBU(1,8-diazabicyclo[5.4.0]undece-7-ene), etc., while reacting at temperature of 20°˜80° C.

This reaction is disclosed on U.S. Pat. No. 4,443,245, and thereafter the final product may be obtained by treatment with acid as the method disclosed on European Patent No. 44,870.

The above compound of formula(III) may be synthesized by the method disclosed on U.S. Pat. No. 4,370,480.

The compounds of general formula(I) can be obtained by reaction the compound of above formula(IV) protected by t-butyldimethylsilane with phenyl carbamate of the above formula(V). ##STR18##

The above reaction may be carried out by adding tetrabutylammonium fluoride in the mixture of carbamate and sulfonamide to obtain the desired product.

In order to prepare carbamate of the above formula(V), amine of below formula(VI) is reacted with diphenylcarbonate or phenylchloroformate under the presence of base as following reaction process. ##STR19##

On the other hand, the compound of the above formula(IV) can be prepared by the following reaction process. ##STR20##

In the above reaction, 2 equivalents of n-butyl lithium is added in t-butylsulfonamide under THF solution at the temperature of -80°˜+50° C. for 1˜24 hrs to obtain dilithio salt, and thereafter ##STR21## is added while maintaining the temperature of -70°˜-80° C. to produce ketone compound. In the above, L is alkoxy, N(CH₃)₂, NCH₃ (OCH₃), etc.

A method for directly lithiating arylsulfonamide is disclosed on J. G. Lombardino, J. Org. Chem., 36, 1843(1971), and also stowell, J. C. "Carbanions in Org. Synthesis", John Wiley & Sons; New York, 1979; Snieckus, V. Tetrahedron Lett. 26, 1145(1985) and ibid, 1149(1985).

It is well known reactions which the lithiated carban ions get up acylation, and hydroxy compound is obtained by reducing ketone with LiAlH₄ or NaBH₄.

A reaction of O-acylation is carried out by reacting the obtained hydroxy compound with acetic anhydride under the presence of pyridine, and easily by use of DMAP as a catalyst. The obtained N-t-butyl-sulfonamide is reacted with trifluoroacetic acid, and then t-butyl group is separated to obtain primary sulfonamide of formula(IV).

This process may be easily carried out by a skill person in field of organic compounding technology in accordance with the method disclosed on J. D. Catt and W. L. Matier, J. Org. Chem., 39, 566(1974), ibid 38, 1974(1973), or in the case of treatment of polyphosphoric acid, J. G. Lombardino, J. Org. Chem., 36, 1843(1971). Then, an excess amount (about 0.3M) of trifluoro acetic acide is used, and the reacting solution is stirred at the temperature of 0°˜50° C. for 1˜72 hrs.

The volatile material of the obtained product is evaporated under vacuum, and then the residue is crystalized in solvent such as diethylether, ethylacetate, etc. In the above reaction process, R1 is a functional group which is stable for high reactive reagent.

Test results indicate that the compounds of the present invention are highly active pre-emergent or post-emergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or post-emergency weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as wheat and barley. Alternatively, the subject compounds are useful to modify plant growth.

The rates of application for the compounds of the present invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formations selected, mode of application, amount of foliage present, etc.

In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modifications or for situations where only short-term persistence is required.

Formulations

Useful formulations of the compounds of formula(I) can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly.

Sprayable formulations can be extented in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (1) about 0.1% to 20% surfactant(s) and (2) about 1% to 99% solid or liquid inert diluent(s). More specially, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactants to activate ingredient are sometimes desirable, and are achieved by incorporation into the formation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J. but other solids, either mined or monufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts.

Typical liquid diluents and solvents are described in Marsden, "Solvent Guide", 2Nd Ed. Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; Solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", M C Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses.

All formulations can contain miner amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques.
